Anaerobic Treatment of Textile Dye Wastewater using Mixed Culture in Batch Reactor
S. Venkatesh Babu*, S. Raghupathy, M. Rajasimman

Anaerobic treatment of textile dye wastewater was carried in a batch reactor using mixed culture obtained from cow dung. The textile dye wastewater was collected from a small scale industry. Statistical design (Response surface methodology, RSM) was employed to study the effect of variables like pH, temperature, textile dye wastewater dilution ratio and MLVSS on dye decolourization and COD removal efficiency. The optimum condition was found for the maximum decolourization and COD removal efficiency. They are: pH – 7.3, temperature – 30.6 °C, wastewater dilution ratio 1:2, and MLVSS – 7000 mg/L. The maximum decolourization and COD reduction was found to be 60.8% and 66.7% at the RSM optimized conditions.
